Todo App (Next.js)

A Next.js todo app with authentication (better-auth) and Prisma (PostgreSQL). Built for deployment on Deno Deploy.

Environment variables

Create a .env file in the project root with:

DATABASE_URL=postgresql://USER:PASSWORD@HOST:5432/DB?sslmode=require
BETTER_AUTH_SECRET=replace-with-strong-secret
BETTER_AUTH_URL=http://localhost:3000

For production (e.g. Deno Deploy), set these in your deployment dashboard. Use your production URL for BETTER_AUTH_URL (e.g. https://your-app.deno.dev).

Commands

• Install deps: pnpm install
• Generate Prisma client: pnpm run db:generate
• Apply migrations: pnpm run db:migrate
• Dev server: pnpm run dev
• Build: pnpm run build
• Start (production): pnpm run start

Deploying to Deno Deploy

This app uses Next.js with output: "standalone" for Deno Deploy.

1. GitHub integration: Connect your repo at dash.deno.com. Deno Deploy will detect the Next.js app and configure the build. Set DATABASE_URL, BETTER_AUTH_SECRET, and BETTER_AUTH_URL in the project Environment Variables.

2. Pre-deploy: Ensure the build runs prisma generate so the Prisma client (under src/generated/prisma) is available. The prebuild script in package.json runs db:generate before next build.

3. CLI deploy (optional):

   pnpm run build
   deployctl deploy --include=.next --include=public jsr:@deno/nextjs-start/v15

Styling

This project uses Tailwind CSS v4 with PostCSS.
